ResumoSeed health testing to detect seed-borne fungi is an important step in the management of crop disease. The main objectives of the study were to isolate and identified the fungal pathogens of three varieties of groundnut seeds in Seiyun, Hadhramout Governorate and two varieties of groundnut seeds in Al-kod, Abyan Governorate. Effect of those fungi in the groundnut seed germination was studied. .The study showed three main fungal pathogens found to be responsible for seed-borne of groundnut varieties seeds namely Aspergillus niger, Aspergillus flavus and Macrophomina phaseolina. The percentage frequencies were 37.63% for Aspergillus niger, followed by Aspergillus flavus representing (26.07%) and Macrophomina phaseolina. (21.02%) of the total isolates .The results also indicated that there was significant difference (p≤ 0.05) in mean isolation frequency of fungi from groundnut seeds at different varieties, Kod-1 variety was the highest, while for seed germination percentage, the results showed there was significant difference (p≤ 0.05) between different varieties, MH variety was the highest in seed germination percentage
